Abstract

A trussed collapsible tubular mast includes a deformable beam having an extended state, a flattened state, and a rolled state, where a stiffness and strength of the deformable beam in the extended state is greater than a different stiffness and a different strength of the deformable beam in the flattened state. At least one collapsible tubular mast wall has a plurality of truss members of a first material having a first material thickness. At least one truss member is disposed substantially perpendicular to a longitudinal axis of the trussed collapsible tubular mast. Disposed between the truss members is a wall area of a second material thickness less thick than the first material thickness.
